The FreeTale client pages (The pages that you are recording action on) do not have to be on the same machine as the server which is recording the users (ft_server).

The FreeTale client just requires HTML and Javascript to run.

The FreeTale server which is running the ft_server, must have PHP5.2+ with PDO/SQLite. This is most common setup for most hosting providers.

Make sure that ./ft_server/db is writable by the user Apache is running as (or if you are just testing chmod 777 ./ft_server/db).
